HighPockets

I just bought a cottage that has an 80 jet Evolution spa. We filled it up this week, turned it on, added the needed chemicals and got the water tested. The issue is that the temperature of the water is registering 105 even though we have it set at 95 degrees. I even turned it on to Economy mode for 5 hours with an outdoor temperature of 65 degrees and the tub is still at 105 degrees. Is there something I am missing? Thanks...
